An autopsy report from the Maine State Medical Examiner's Office concluded that 52-year-old Marilyn Rider died from a morphine overdose last November. Rider's live-in boyfriend, Roy Gordon, found her dead in her apartment at 103 Silver Maple Lane on Nov. 11. She was last seen alive the night before at a birthday party for Gordon.

Farmington Police Chief Jack Peck said Gordon has been charged with aggravated trafficking in a schedule W drug which caused the death of another person, three counts of unlawful furnishing Schedule W drugs and one count of falsifying evidence.

Also arrested on charges of aggravated trafficking Schedule W drugs which caused the death of another person was Terry Oliver, 53, of Wilton, Peck said. Oliver also faces two counts of trafficking Schedule W drugs.

Seth Gordon, 23, of Wilton and Erick Barnes, 27, of Industry, were both arrested on charges of unlawful furnishing Schedule W drugs which caused the death of a person while Scott Kidder, 32, of Wilton was charged with one count of furnishing Schedule W drugs. Barnes also was charged with one count of falsifying evidence.

Roy Gordon and Barnes are accused of removing evidence from Rider's apartment before police arrived, Peck said. He did not know whether Roy Gordon and Seth Gordon are related.

All five people were booked at the Franklin County Jail in Farmington. Bail was set at $75,000 cash for both Roy Gordon and Oliver; $50,000 cash for both Seth Gordon and Barnes and $15,000 cash for Kidder.
